Description
Technical Field
The utility model relates to a transformer manufacturing field especially relates to a transformer is with two E type silicon steel sheets.
Background
The transformer consists of an iron core and a coil, wherein the coil is provided with two or more than two windings, the winding connected with a power supply is called a primary coil, and the other windings are called secondary coils. The core acts to enhance the magnetic coupling between the two coils. In order to reduce eddy current and hysteresis loss in the iron, the iron core is formed by laminating a plurality of silicon steel sheets.
In the prior art, the heat dissipation performance of the silicon steel sheets is poor after the silicon steel sheets are laminated into the iron core, so that the temperature of the transformer is high after long-time high-power work.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is that the silicon steel sheet among the prior art is good thermal diffusivity after folding into the iron core, and it is higher to lead to the long-time high-power work rear temperature of transformer, the utility model provides a transformer is with two E type silicon steel sheets to solve above-mentioned problem.
The utility model provides a technical scheme that its technical problem adopted is: the double E-shaped silicon steel sheet for the transformer comprises a body, wherein the body is provided with two E-shaped winding grooves, the two E-shaped winding grooves are bilaterally symmetrical and are connected, and heat dissipation fins are arranged at the edges of the E-shaped winding grooves.
Further: the E-shaped winding groove is provided with heat dissipation holes.
Further: the number of the heat dissipation holes is multiple, and the heat dissipation holes are uniformly distributed on the E-shaped winding grooves.
Further: the body is provided with an installation positioning hole.
Further: the shape of the heat dissipation fin is E-shaped.
The beneficial effects of the utility model are that, the utility model relates to a transformer is with two E type silicon steel sheets can effectually distribute away the heat of transformer through setting up louvre and heat dissipation wing, avoids the transformer high temperature, simultaneously through setting up the installation locating hole, can guarantee the position precision of pressure in the installation of silicon steel sheet, avoids the silicon steel sheet to take place the quality that the skew influences the iron core.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural view of a double-E-shaped silicon steel sheet for a transformer of the present invention.
In the figure, the winding groove is 1, E-shaped, the radiating fin is 2, the radiating hole is 3, and the mounting positioning hole is 4.
